How Many Lights on one Breaker ?

plug_messAlways the big question, how many lights on one breaker

I’m ask so many times how many outlets and or lights can I put on a 15 amp or 20 amp breaker. Well NEC code does not have it listed that way. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker. Now this is of course they are 120 volts 60 Hz (USA or Canada).

Kitchen But let’s think of a kitchen or dining room. Just the name kitchen tells says “Countertop Microwave, blender, toaster, toaster oven” And that’s just my house. Turn all those on at once and BAM You are over and the breaker will trip. That’s why code with kitchens is very different. For a kitchen it’s 20amp and something like two outlets per breaker and no more than four feet apart of counter space. And any counter that is more than two feet long needs an outlet. And all countertop outlets must be GFCI protected.

Garage Now in a garage, code states that you only need one GFCI protected outlet. Now that’s just dumb and cheap to install one outlet in a garage anyway. But hey each to their own right.

Bathrooms Bathrooms must also have one GFCI outlet (20 amp)

So let’s say you’re wiring a simple bedroom. My rule of thumb and code is. An outlet within six feet either direction of the bedroom door and within 10 feet from there all around the room. So plan carefully when you get to the closets. Some simple planning and you’ll be fine.

That’s how I wired my house. And when we lost power during hurricane Sandy we had all the lights in the house working on a generator. But that’s another story altogether.

I am an electrician and there is a code, it’s 80% of the rated circuit breaker. Ex- 12 plugs on 1 15 amp breaker.

“Now this is of course they are 120 volts 60mhz (USA or Canada).”

Uh, no way! The North American power grid is 60Hz AC, not 60mhz.

Same as Rick how to install a transfer switch, when the sevice lines are live, can it be done without calling elec. company to disconect. Whole house transfer, not just individule circuits.
Thanks.
